<p>今天，书店老板有一家店打算试营业 customers.length 分钟。每分钟都有一些顾客（customers[i]）会进入书店，所有这些顾客都会在那一分钟结束后离开。<br>在某些时候，书店老板会生气。 如果书店老板在第 i 分钟生气，那么 grumpy[i] = 1，否则 grumpy[i] = 0。 当书店老板生气时，那一分钟的顾客就会不满意，不生气则他们是满意的。<br>书店老板知道一个秘密技巧，能抑制自己的情绪，可以让自己连续 X 分钟不生气，但却只能使用一次。<br>请你返回这一天营业下来，最多有多少客户能够感到满意的数量。</p>
</blockquote>
<blockquote>
<p>示例：<br>输入：customers = [1,0,1,2,1,1,7,5], grumpy = [0,1,0,1,0,1,0,1], X = 3<br>输出：16<br>解释：<br>书店老板在最后 3 分钟保持冷静。<br>感到满意的最大客户数量 = 1 + 1 + 1 + 1 + 7 + 5 = 16.</p>
</blockquote>
<p>6ms。首先算出不发动技能的时候，所获得的满意人数。然后再遍历grumpy数组，以x为窗口大小，左边出去对应的操作，和右边进来对应的操作，具体操作在下面的注释里面。</p>
